Hey guys, Just got my machine running.

I have the following:

Gigabyte GA-8N-SLI Rev 1.1 Running Bios F4
Pentium D 805
1GB Corsair DDR2-800 Twin2X
Gigabyte 3D Galaxy Liquid Cooling System
Aopen AO700-ALN 700W Power supply

Currently running at 3.8 stable without changing the voltages.

CPU temps are 38 on idle and 45 on load.
 
Ok still running on 3.8 but it was crashing when i put a heavy load on it so now i upped the voltage to 1.4v and its stable stable now

okay when you say running stable what do you mean by that? im wondering if overclocking at 3.8ghz could be left on for how ever long and not ever crash?

andd. what does everybody recommend as far as "best ddr 2 memory?"
 
Well im running prime95 on loop for a while now and SuperPI at the same time.

No crash yet. And im browsing at the moment 🙂
 
3.6 is common - 4.1 is rare and requires WATERCOOLING

I just don't see it, your mobo and DDR2 memory eats up any savings I don't see this as an Opty killer? Maybe if you could hit 4.1 on a $65 mobo with old ddr400 (without losing major perf) and do all this on air i'd throw you a bone .. l8r keep dreaming

Please... you are asking too much! You seems kind AMD owner!

the ram doesn't make that much of a difference, and you don't have to buy an expensive board, and your pretending like people don't get nice mobos for the amd's. the power consumption on the ddr2 is better i believe too.

Hmm a p4 at 3.6-4.1Ghz runs like azz without dual-channel DDRII, cause ddrI-380 vs. ddrII-760 lol. If you don't get a 955x, 975x it probably ain't going to happen cause of cheapo traces, nerfed memory ratios/options, or cut-rate VRM power parts (not just any mainboard can hold 230w cpu stable m8). Buying a premium AMD mobo is a choice w/ intel it's a req. in this case. ddr2 won't mean much on a cheapo mb cause your never see DDR2-667 let alone 800+ which is needed to make this setup happen.

My point was this is susposed to be a ocr's dream I don't think so if you have to go premium on all the pieces to make it happen.

it's not like your going to be running it at full load 24/7 the whole year anyways. if you did, i'd be asking what on earth your doing?...

Folding

a doubt the average user is going to be doing whatever that is...

well, how about 24/7 for a month or so. i download files from games to movies
 
If for you it is simple to manage the CPU speed (maybe with the right MB software), you can increase the power only when you play or use applications that significantly need more power.

If you leave the computer on all the night to download music or movies, it
is not necessary to have 4.1GHz!!
 
I loved the artical. One question I have is that is DDR-677 memory used throught the overclocking. I would like some info on what memory was used for this.
 
can anyone answer this questiong.... and Opty @ max OC (2.9-3ghz) or a Pentium D 920-930 @ Max OC on air.... not water.... if we are comparing OC's.... we should compare the cooling method as well..... water is more expensive.... and less practical..... I have been unable to find an article benchmarking these two..... and I am curious since just about every 9XX should break the 4ghz barrier... I am curious about "upgrading" to a 9XX IF it will hit 4.5 on air... and be faster than my Opty, mainly for a path to Conroe... and someone is buying my Opty, mobo, and memory..... Any help?
 
Pretty much late getting my 2 cents in here, but it's both amazing and also disappointing.

Amazing because you're getting 4.1 GHz speed for the price of a 2.66 Ghz, and it works well and so stable.

Disappointing because you, THG people should have in all fairness compared the 965 EE and put that CPU through the same tests.

No, I am not paid by intel and I don't bash the editors here, but if you're going to do an article on which chips that have the overclocking potential, don't turn a blind eye to comparing another highly overclockable CPU.

The 965 EE also has an unlocked multiplier, so it can also do 20x, and has actually been used with LN2 to get a WR of something in the range of 7.23 GHz peak and 6.8 GHz stable. A similar setup using phase change cooling has been shown to give speeds around 5.23 GHz stable.

True, that CPU will cost you over $1000 as opposed to $130. But even if the difference in price equals the price of a phase change cooler, the voltage limits of the 805 won't allow even a phase change cooler to push it over the 4.1 GHz limit much.

Correct; the article has shown that for $130 you can get a CPU that will beat a stock 965 EE in many applications.

Wrong; the article forgot to mention that the 965 EE can be overclocked just as easily with the right equipment and acheive even greater performance benefits.

As I have said to this editor before, get your hands on a Mach II GT, a 965 EE and a P5WDG2-WS. See what this combination gives you and then go write your article!

Guess Again!! missed the other news!! 7.1GHZ OFF THIS CPU WITH LIQUID NITROGEN!!! So yes, $130 well spent.

That should add another 8 pages. 😛
 
I bought a 805 yesterday and it clocked to 3.33 like nothing. I cant get it any higher though. Obviously its because of the other components but is it the motherboard ,the motherboards chipset or the ram ?

Epox 5P945-J Mobo
Samsung DDR2- 667 RAM
 
Dont know about everyone else but I got 3.8Ghz on a cheesy ECS mobo that cost 68$ so how premium it is I dont know lol I think with some good cooling more would be possible but 3.8Ghz is plenty enough for me im stopping there :)
 
*disclaimer* I am just letting you all know I'm not an expert in anyway shape or form. I'm just here to rant a bit.

Let's start with the people against AMD bashing - It's okay for AMD fans to completely bash "the man" intel all the time, but if intel has anything worth ANYTHING you all feel the need to downplay it and make it seem so silly? That's the same as thinking linux is going to all the sudden be the OS of choice tomorrow. Get a life.

Next - to the people who seem to think this is a horrible deal for a "common consumer" - How many common consumers go out and over clock? How many consumers just buy parts and assemble a computer themselves? I'm pretty sure most "common consumers" go to Best Buy or some retailer, so get off that idea.

Next, to the guy bashing Tom's hardware's credibility. What's wrong with someone having a very well written article with information for both the newb and guru posted about the subject they were trying to put out? The article title stated "A 4.1 GHz Dual Core at $130 - Can it be True?" They could have clocked it at that for .0000000000001 seconds, and if it did, the article's subject was acheived.

I personally don't see this as a bad deal at all. I wish people would stop being so biased because their "underdog" AMD is getting shown up. I wish the hardcore Intel guys wouldn't smear it in AMD's face. I also can't stand the "apples to apples" complaint. "Compare it to this then!" One thing I think about, how much will everything cost and then how well will that perform? If it saves me even 50 dollars to go with overclocking, I'll overclock.

This IS a good deal. Its a VERY nice upgrade for me, and for pretty cheap. It can be for a lot of people, quit trying to force what is good for YOU on everyone else.

Intel needs AMD, and AMD definately needs intel. I'd like to see what would happen if Intel just haulted production on everything and let AMD try to carry the load by itself.

I like both processor companies, I'm not biased, this seems like a nice upgrade. For once I'm happy to see Tom's Hardware not bashing Intel. I think showing both side's pros and cons is how every site should work.

As for the power consumption. Just turn off the bedroom light when you leave.. plus.. half of us geeks live in the dark anyway so you could just say you're breaking even with what you would normally spend as a "typical consumer" in a household.
 
Doesnt sound so impressive to me. Just look at the facts.
Did the person just get lucky? Have others tried to oc theres to 4.1?
The real question here is how long before it burns up?
If Intel thought they could clock those to even 3.2 and sell them, they would. But they dont, probably because they dont last.
 
I plan on overclocking my 805 to 3.6ghz. Will this setup be able to hold it?

It is amazing that thg got it to > 4ghz, but what I think we should be looking at is how cheap this processor can be overclocked to 3.6/3.8 on air. The focus should be on defining the cheapest motherboard/memory/psu combination which gives a reliable system at these values. For the majority of people this will be what they want.

1st make sure u hv sufficient cooling - fan & ventilation.

For your system, 3.6 at stock voltage should not be a problem, even 3.8 with voltage adjustment is possible.

4.1 is just crazy UNLESS u have water cooling onwards...

p.s. to all using gigabyte 8n sli, DO NOT upgrade bios to f5 as will cause system to cease functioning due to unknown incompatibility. CPU not supported.
